My 91 honda accord lx wont start, so i replaces the spark plugs, spark wires, cap, gasket valve, and it still wont start, it turns over but doesnt start?

Get the codes for that check engine light read by any autoparts store and let us know what it says.

DO A SMALL TUNE UP REPLACE SPARK PLUGS AND WIRES, REPLACE DISTRIBUTOR CAP AND ROTOR, REPLACE FUEL FILTER AND AIR FILTER. IF YOU ARE GETTING FUEL AND SPARK. EITHER IGNITION OFF OR VALVE TIMING OFF YOU VECHICLE HAS A TIMING BELT AND TENSIONER IF TIMING BELT SLIP TIMING IT WILL THROW OFF VALVE TIMING MAKING IMPOSSIBLE TO START CAR.

There is a sensor under the left hand side of the dash that would not allow it to start, provided that you have replaced the electronic spark module inside the distributor first, which is what it sounds like it would be, When you say you replaced the distributor I assume you replaced it complete!

cars wont start without fuel so it could always be A) fuel pump B) fuel filter C) fuel injecters dirty. any one of these will cause fuel not to reach your spark plugs and cause then eng not to start

i am thinking that the 15 amp fuse is the fuse that protects the ecm circuit replase the O2 sensor wires and check the harnes for a shorted wire.

sticking valves. the short run of the engine free's them enough to enable runnig

I like to make sure the timing belt is not skipped or broken by watching the cam turn inside the valve cover. Then I lay a spare spark plug on valve cover connected to any plug wire to see if it sparks. Fuel can be confirmed by smelling the exhaust, or by using starting fluid . These cars are famous for a coil relay solder break problem. The relay is heat expansion damaged, its mounted high up in the dash drivers side corner it is about 3" square gray.

It may be the O2 sensor. I know it's not the fuel filter, spark plugs, spark plug wires, Vehicle Speed Sensor, Dis. cap, or TCM.

I would remove the distributor cap and crank the engine over . If the rotor does not turn , then you need to replace the timing belt. The timing belt needs to be replaced every 60 K. If the rotor turns then make sure you have spark to a spark plug. Run a compression test on each cylinder. The basics to run are compression, spark, fuel and timing.

did you replace the the plug wires right i would double chect them and make sure and check the disribotor. and try runing some fuel injector clener through it. after you check all that can you start it with starting fluid
